The project contractor will close all eastbound lanes from 12:01 to 5:00 a.m. between Somersville Road and Lone Tree Way so concrete paving can be done in the freeway median, according to a Caltrans news release.

Motorists will be directed off the highway at Somersville Road and down Delta Fair Boulevard to Buchanan Road and Putnam Street to Lone Tree Way, where they can get back on the freeway.
